1.兩個(gè)ASBR(VMX4-P4,VMX5-P5)各有EBGP和IBGP連接,協(xié)議族bgp-lu(family inet labeled-unicast)
為兩個(gè)PE（10.0.255.1咐扭，10.0.255.6)提供labeled route
2.PE的IBGP( family inet labeled-unicast resolve-vpn), resolve-vpn表示將labeled route放在int.3,為跨域(inter-AS)PE之間的VPNV4路由的下一條提供解析
Allow labeled routes to be placed in the inet.3 routing table for route resolution. These routes are then resolved for PE router connections where the remote PE is located across another AS. For a PE router to install a route in the VRF, the next hop must resolve to a route stored within the inet.3 table.
resolve-vpn—(Optional) Store labeled routes in the inet.3 or inet6.3 routing table to resolve routes for a provider edge (PE) router located in a different autonomous system (AS). For a PE?router to install a route in the virtual routing and forwarding (VRF) table, the next hop must resolve to a route stored in the inet.3 or inet6.3 routing table. This option is also used to configure inter-AS VPLS with MAC operations.
